I've got the same problem. When you compile the list.cc file, the compiler
doesn't know, that you want to use integers in intlist.cc for the templates.
Therefore the Linker returns an undefined reference to the List<int>
functions. If you have the definitions together with the declaration in 
the header file, the program will work. But there should be another
compiler specific solution to this problem, which I haven't found yet.
Any help would be appreciated.
